The escalation in demand for textile products increased the use of fresh water and treatment of wastewater; which escalates the search for suitable and energy-efficient technology for wastewater treatment. Solar assisted technology ( i.e. solar desalination) for the textile industry wastewater treatment is proved to be an affordable technology. The only drawback of solar desalination is its low productivity which is the major hindrance in the global acceptance of the system. In the present study, an ingenious improvement in form of a parabolic concentrator-based solar desalination system (PCB-SDS) is designed to overcome low productivity, and the simultaneous use of source textile industry wastewater for its treatment makes this study more realistic. The performance of the designed system was examined for three different brine depths i.e. 20%, 40%, and 60% for two different processing step i.e. Dyeing and Degumming. System performance was evaluated in terms of energetic, exergetic, pollutant removal, and economic analysis. The maximum output of the system was found to be around 7440 and 8330 mL/day on clear sunny days with textile dyeing wastewater (TDyWW) and textile degumming wastewater (TDgWW) at 60% depth respectively. Daily average energy and exergy efficiency of system varies in the range 39.8–51.9 and 3.6–4.8% respectively. The degumming wastewater shows 85% COD removal, whereas, around 90% of TDS and hardness removal was also recorded. The dyeing processed wastewater showed 80% COD removal efficiency, ≅90% TDS, and hardness removal. The cost per liter of distillate output produced from designed PCB-SDS was found to be 0.014 $/L.

Textile industry processes produce some of the most heavily polluted wastewater worldwide. Wastewater from textile industry is also highly variable (it varies with time and among factories) and contains wide diversity of pollutants. This makes the treatment of textile industry effluents, complex, site-specific and expensive. Numerous combinations of wastewater treatment technologies are currently applied in the textile industry, yet methods that work for one emitter are often unsuitable, insufficient, not necessary or unsustainable to another. As textile industry evolves, its water treatment research also has to keep pace with increasing demands. The broader aim of the textile industry wastewater treatment is to maximize the efficiency of pollutant removal, while releasing effluents that society considers as being environmentally acceptable or safe. In the last ten years great strides have been made in the ability to lower the biological oxygen demand (BOD) and ammonium (NH4+) in wastewater. These advances elicit the question: can intensifying the usage of such technologies in the textile industry also increase its efficiency? The research team analysed water treatment by aerobic biomineralization via microbial biofilms immobilized on solid surfaces and hosted in Moving Bed Bio-Reactors (MBBRs). These biofilms are selected for carbon oxidation and ammonia oxidation. The authors compare the potential of active sludge biotreatment with the performance of MBBRs. The results are used to evaluate the potential of MBBRs as a cost-reducing solution in textile wastewater treatment plants. Our analysis supports that upgrading such stations to more heavily usage of MBBR biotechnology would increase their sustainability and environmental friendliness. The authors also discuss research directions and milestones for expanding the effects of MBBRs on the textile industry wastewater treatment.

The increment of Songket popularity as the traditional fabric from South Sumatra increases the production of Songket and the wastewater produced during the dying process. The dying process produces the reddish wastewater, and if it is disposed of directly into the environment, it will have a negative impact on the waters. The wastewater treatment of this reddish liquid is by electrocoagulation method. Electrocoagulation method is contaminants removal by electrical and chemical treatment system. The electrocoagulation method in this research was conducted in a batch where the wastewater was treated using 16.5 x 7.0 x 0.2 cm aluminum electrode. The parameters varied were the current density and processing time to determine the pH value, color intensity, BOD5, COD, TSS, and phenol levels. The optimum condition obtained from this study at a current density of 25 A/m2 with a processing time of 160 minutes. The effectiveness of Songket wastewater electrocoagulation was 67.28% for TSS, 54.13% for BOD5, 63.64% for COD, color intensity 79.21% and phenol content of 74.93% respectively. The result has fulfilled the quality standard of textile industry wastewater treatment.
